possible current. The converter is then disabled when stopped.
Ignore No reaction is present. A warning message can be output via a
digital output.
Not all alarms can initiate a controlled stop of the drive. The possibility of setting the
particular “Activity” for individual alarms is described in the table below.
Latch ON The alarm is stored. The programmed actions (e.g. opening
the OK relay) are enabled. This status is kept latched even if
the fault condition is restored. A Reset command is required
before a restart.
OFF In case of alarm, the drive is disabled and the programmed
functions are enabled. The alarm is not latched. When the
failure is removed, the alarm is automatically reset and the
device tries restarting.
Ok relay open ON An alarm causes the opening of the potential isolated contact
between terminals 35 and 36.
OFF The alarm does not cause the opening of the potential free
contact of the OK reay.

Hold off time Delay time between the alarm condition detection and the alarm activation. If an alarm
condition occurs the alarm stay OFF for the Hold off time. When this time is elapsed
and the alarm is still present, the alarm activates.
Restart time If Latch=Off and the alarm condition persists even after the time defined via Restart
time, the alarm is stored and no restart is possible (Latch=OFF).

! In Terminal mode to reset the fault the terminals enable and start must be at zero voltage. The
occurrence of a failure is indicated in the display of the keypad. If “Latch”=ON is selected, a
Reset command is necessary. This can be carried out, for example, by pressing the CANCEL
key on the keypad. If a second error occurs before the first one was reset, the text “Multiple
failures” will appear in the display. In this case, a reset is only possible via Failure reset
parameter in the SPEC FUNCTIONS menu. The reset can be obtained by pressing the ENT
key with a disabled inverter.
Failure supply Failure on the supply voltage.
It indicates a failure on the internal voltage of the regulation circuit. The message “Failure
supply” occurs if an enabled converter has no voltage on the U2 and V2 terminals. If
it is of a short duration and restored, a possible digital output prepared for the message
is set to a Low condition. A normal reset can be carried out.
